I purchased Photoshop CS6 and installed it on my old computer. Attempting to reinstall it on my new computer, it said I needed my serial number. I couldn't find the box with the serial number on it, and so went to the licensing website to try and recover it. Unfortunately, after logging in, it said that I had no Adobe products.
How do I go about recovering my serial number so that I can reinstall Photoshop?
You can keep trying Customer Service, but if you have not registered your product, or have proof of purchase there is little that can be done.
Here are their phone numbers, hopefully you can sort something out.
